IMPROVEMENT IN HARVESTER-CUTTERS.

Specification forming part of Letters Patent No. 91,102, dated June 8, 1869.

To all whom it may concern:

Be it known that I, G. L. DU LANEY, of

Mechanicsburg, in the county of Cumberland and State of Pennsylvania, have invented new and useful Improvements in Harves ter-Cutters; and I do hereby declare that the following is a full and exact description thereof, reference beinghad to the accompanying drawings, and to the letters of reference marked thereon.

Figure 1 is a perspective view of the sicklebar, showing the cutter-blades in position. Fig. 2 is an end view of the sickle-bar, showing the manner of securing the cutter-blades to the sickle-bar by means of the stay-loops. Fig. 3 is a top view of the cutter-blade, showing the position of the slot that receives the stay-loop.

The nature of my improvement consists, first, in the peculiar shape and manner of constructin g the sickle -bar of harvesting-machines; secondly, in the peculiar construction and arrangement of devices by which the cutter-blades are secured to the sickle-bar.

To enable others skilled in the art to make and use my improvement, I will proceed to describe its construction and arrangement.

The bar D, to which the cutter-blades a are attached, is constructed of the form and shape of the letter V, and at such an angle as will insure to the slot B such a bevel as will securely hold the stay-loop V in position when passed up through the slot B and locked in the blade a.

By this peculiar construction of the sicklebar D the stay-loops V are not only held securely in position, but the sickle-bar is itself very greatly strengthened, and less liable to bend or break in case the cutters become choked or otherwise obstructed.

The bar D is provided with a stay-pin, I, against which the blade c rests. The bar D is further provided, at its opposite end, with a drag-screw and nut, O, that secures the blades in position, when placed on the bar D, (see Fig. 1,) by being screwed against the blade a at the end of the bar D. The cutter-blades a a a are constructed of any desirable shape or size, and are provided with a beveled slot, B, about their center, for the purpose of admitting and securely holding in position the stayloop V, that secures the blades to to the sicklebar D.

The stay-loops V are so constructed as to exactly fit into the slot B of the blades a, and of such shape as to exactly correspond to and fit over the bar D. (See Fig. 2.) loops V may be slightly flared at each end, so as to give them a wedge shape, that will the more securely hold them in position and prevent their being forced up through the slot B of the blades to in case the free action of the cutter-blades a is in any way obstructed.

After the several parts of my harvester-cutter have been carefully prepared, as above described, the stay-loops V are placed in the slot B of each cutter-blade, passed up and through each slot sufiiciently far to admit the sickle-bar D between the stay-loops V and blades to, thus effectually securing the cutterblades to to the sickle-bar D by means of the stay-loops V and slot B.

After a sufiicient number of blades have been secured to the bar D, as above described, the nut G is drawn against the blade a next to the end of the bar D, thus compactly and substantially securing the whole in position.

Having fully set forth and described my llllprovement in harvester-cutters, what I claim, and desire to secure by Letters Patentof the United States, is-- 1. The sickle-bar D, as shown and described, and for the purpose specified.

2. The stay-loop V, as shown and described, and for the purpose set forth.

3. The beveled slot B, draw-nut (J, and stay-pin I, when used in combination with the sickle-bar D, and stay-loop V, as shown and described, and for the purpose specified.
